benefit other climate research and analyses interests. CEOP has
gained the attention of other international organizations outside of
the WCRP community, as evidenced by the proposal for an
Integrated Global Water Cycle Observations (IGWCO) theme within
the framework of the International Global Observing Strategy
Partnership (IGOS-P), which has re-affirmed CEOP as ‘the first element of the IGWCO’. As you are well aware, IGOS is a partnership
between international bodies concerned with global environmental
issues, including, among others, all the space agencies belonging to
the Committee on Earth Observation Satellites (CEOS).
Prof. A. Sumi

Dr. J. KayeThe successful launches of the NASA Terra and AQUA, the
NASDA ADEOS-II and the ESA ENVISAT earth observing satellites
have started a new era in climate system research. The instruments
on board these spacecraft are already adding new content to theflow of data that has begun to arrive from earlier Earth system satellites, e.g. TRMM, GRACE, Jason 1, SAGE III, and the existing suite ofoperational meteorological satellites. Within the international
research framework we have closely co-operated with the World
Climate Research Programme (WCRP) in the development of large
multi-disciplinary climate research studies such as the Global
Energy and Water Cycle Experiment (GEWEX), which is successfully
addressing water resources applications issues. Many aspects of
our own national priorities parallel those within the international
community including the building of new global descriptions of the
Earth’s environment, upgrading prediction models and improving
descriptions of key local and regional processes. The global products and data sets derived through the exploitation of new satellite
sensors will be critical to these developments and will significantly
extend our current knowledge.

It is in this context that we have accepted the role of Co-Chairs of
the CEOP Advisory and Oversight Committee (AOC). We haveagreed that the primary role of the AOC will be to provide constructive feedback to the CEOP Scientific Steering Committee (SSC) and
its Working Groups on the relevance of CEOP goals and objectives
as well as the importance of the scientific return from CEOP activities to national bodies and organizations that sponsor CEOP andsupport its contributing scientists. The AOC will work in concert with
the CEOP Lead Scientist, Dr Toshio Koike, and with the CEOP SSC,
chaired by Dr Hartmut Grassl of the Max Planck Institute, Hamburg,
Germany.

Our own participation in the unique international scientificendeavor of the Coordinated Enhanced Observing Period (CEOP) has
been motivated by our desire to promote work that could improveprediction of the climate system by focusing on the measurement,
understanding and modeling of water and energy cycles. It is important to ensure that CEOP takes into account the requirements of theclimate research community at large in planning the assembly of
coordinated data sets that will serve numerical modeling needs and• UNIQUE OVERSIGHT REQUIRED TO EXPAND EARLY

of annual cycle (October 2002 through March 2003) will be submitted to the CDA, in the agreed format, so that Category 1 data would
arrive on or before 1 October 2003 and Category 2 data would follow on or before 1 June 2004. All of the CSE Spokespersons,agreed to meet these submittal dates.
The main issues related to the Satellite Integration element of
CEOP that were discussed at the Berlin meeting included: That a
proposal to obtain subsetted satellite data from 250 km grids centered at each CEOP reference site would be prepared and presented
to ESA and EUMETSAT on behalf of CEOP by the Chair of the CEOP
Science Steering Committee, Dr H. Grassl with Jürgen Fischer; that
CEOP satellite data requirements encompassed Level 1b (referencesite), Level 2 (reference site and for monsoonal regions) and Level 3(global) data products; that the size of the files (particularly the Level
2 for monsoonal regions) needs to be investigated along with suitable means for transfer of the data to the CEOP Satellite Data
Archive Center at the University of Tokyo; and that the data set format and phased release schedule have been agreed upon.
In keeping with efforts to unify and integrate data sets for analysisof the water cycle, composite products of the in-situ data at the reference sites, satellite data and model outputs now being generated
and analyzed were shown at the meeting.
The CEOP Water and Energy Simulation and Prediction (WESP)
activity plan was presented at the meeting. The plan has the detailsof the main elements of WESP, which includes building on the
GEWEX WEBS; adding transferability projects that currently have a

direct link to CEOP; focusing on land data assimilation projects; anddiscussing the nature of the data being requested to achieve thegoal of identifying model processes and state variables that can becompared to in-situ and satellite measurements and to then develop
community intercomparison projects that can help to define andquantify measured and modelled processes. The latest version of
the WESP Major Activities Plan (MAP) can be accessed on theInternet through the CEOP Data Management site at:
http://www.joss.ucar.edu/ghp/ceopdm/.
It was reported that a targeted workshop on "The Role of theHimalayas and the Tibetan Plateau within the Asian Monsoon
System" had been organized on behalf of the CEOP Monsoon
Systems Studies Working Group. The workshop was to take place in
Milan Italy from 7 to 8 April 2003. The workshop was to be hosted
by the Epson Meteo Centre (CEM) with support by the Ev-K2-CNR
Project (Gianni Tartari) and WCRP. The outcome of the workshop is
to be summarized in a draft report.

The CEOP/GEWEX Workshop on "The Role of the Himalayas andthe Tibetan Plateau within the Asian Monsoon System" was held on
7-8 April 2003 at the Epson Meteo Centre, Milan, Italy, hosted by
Epson Meteo Centre and the Ev-K2-CNR Committee with support
from the World Climate Research Programme (WCRP) Global Energy
and Water Cycle Experiment (GEWEX).
In recognition of the profound thermal and dynamical influenceexerted by the Himalayas and the Tibetan Plateau on the Asian
Monsoon System, it was important to briefly review the current
understanding of physical processes occurring on these high-altitude and extended regions, and to examine their relation and influence on the global monsoon circulation at different spatial and temporal scales according to the CIMS (CEOP Inter-Monsoons Model
Studies) strategy.
In summary, the following issues and recommendations werehighlighted:

4 was strongly encouraged; key physical processes wereaddressed.
2. Monsoon understanding and predictability has to be improved following a downscaling strategy with integration and cooperation
among reference sites and remote sensing observations andmodel analysis and simulations. Improvement in model physics isneeded.
3. Monsoon issues, especially related to seasonal-scale processes,
intra-seasonal oscillations and their relationship with local hydroclimate, were highlighted and it was suggested to proceed
through coordinated model integrations from GCMs (General
Circulation Models), through RCMs (Regional Climate Models) to
CRMs (Cloud Resolving Models) under the CIMS strategy.
4. Coordination with CEOP WESP (Water and Energy Simulation andPrediction), connection with GEWEX/CLIVAR and cooperation with
the Asian Brown Cloud (ABC) experiment were recommended.

In order to understand what components of the global water andenergy cycles can be simulated and predicted at regional and global
scales, CEOP has undertaken the generation of unified and integrated
data sets for the water cycle studies as an essential element of its
implementation strategy. The Enhanced Observing Period 1 (EOP-1),
from the period from July to September 2001, was designed as the firstchallenge to CEOP plans for the production of composite data sets. The
successful archiving of the in-situ data at the reference sites, satellitedata, and model outputs, was required for EOP-1, which became theprecursor to the annual cycle enhanced observation periods, EOP-3 andEOP-4. The prototype CEOP EOP-1 composite products are available on
the Internet at: http://www.joss.ucar.edu/ghp/ceopdm/.
Plate 1 is the first view of the composite products of the CEOP EOP1 data sets. The figures fringed with red and blue lines show the 10-day
averages of net radiation (Rn) and sensible heat flux (H), respectively, atthe twelve reference sites where Rn and/or H are available. In the figures, the red and blue bars indicate the data from in-situ observations
at the reference sites and the Model Location Time Series (MOLTS) output generated by the NASA/Global Model Assimilation Office (GMAO,
formerly the DAO), respectively. The observed Rn exhibits the latitudinaland seasonal variations at all reference sites except Lindenberg where
Rn is consistently much smaller than at the other sites even in summer
due to local climate conditions. The GMAO/MOLTS Rn is in good agreement with the observed Rn at many reference sites except at

Lindenberg and Rondonia. During EOP-1, there was only a limited
amount of sensible heat flux data available. They show apparently that
there exists a bigger gap between the observed H and the
GMAO/MOLTS H.
The figures fringed with green lines show the profiles of the atmospheric temperature (Ta) and the relative humidity (RH) observed at threereference sites and analyzed with the Scripps Experimental Climate
Prediction Centre (ECPC) model. The ECPC model Ta indicated by the
red line corresponds well to the observed Ta shown in green, at the reference sites. It is possible to conclude from this that the 4DDA for air
temperature is working very well. On the other hand, the ECPC model
RH misses several important peaks as well as the detailed structures in
the observed profiles and shows a big gap in the upper troposphere.
During the on-going EOP-3 from October 2002 to September 2003,
CEOP will archive a full complement of observation parameters from 36
different reference sites located around the world, model outputs from
10 numerical weather prediction centers and satellite data will also becollected. More comprehensive and detailed aspects of the global water
cycle will be uncovered with the unified and integrated EOP-3 data sets.

The two advanced microwave radiometers (AMSR-E and AMSR)
developed by the National Space Development Agency (NASDA) of
Japan were launched on board the NASA Aqua and NASDA Midori2(ADEOS-II) spacecraft in 2002. The instruments are working well as
they continue to provide valuable data for regional and global water
cycle studies. In June 2003 NASDA began providing theAqua/AMSR-E data to the international science community. As acontribution to CEOP, they are also providing the AMSR-E, TRMM
and SSM/I products associated with CEOP reference sites.
Both AMSR-E and AMSR have low frequency channels at 6.9 GHz
with acceptable spatial resolution, 70 km and 50 km, respectively.
For all currently available data, they have the capability to provide
soil moisture monitoring for regional and global scale water cycle
process studies and modelling. The accuracy of this capability, however, is dependent on how well their soil moisture products can bevalidated.
As Figure 1 shows, twelve soil moisture observation stations(yellow circles) were established in the 120 km by 160 km rectangular area of the Mongolia reference site as well as 6 Automatic
Weather Stations (red circles). The arrangement of these stations
took into account their spatial resolution and the soil moisture heterogeneity of the site. The upper chart in the Figure 2 is the resultof a validation, process, which applied the AMSR soil moisture algorithm developed by the University of Tokyo to the observed soil moisture at 3 cm depth at each ASSH station and the nearest actual
AMSR-E instrument data. Due to the large heterogeneity, the results
scatter considerably. The lower figure shows the result of the validation using the spatial averages of the in-situ and satellite observations. The average relative error is 2% from July to September
2002.
By using the validated algorithm, 10-day average soil moisturemaps have been created for Mongolia for the period of July throughSeptember 2002 (Figure 3). These maps will be validated by thenation-wide operational soil moisture observation data and theresults will be reported in due course.

CEOP reference sites in the LBA Continental Scale Experiment
José A. Marengo, LBA Representative at CEOP, CPTEC/INPE, São Paulo, Brazil
Luiz Horta, LBA DIS Manager, CPTEC/INPE. São Paulo, Brazil
As part of the LBA experiment, several projects funded by NASA,the European Union, and the Brazilian Government (FINEP, FAPESP,
CNPq, among other agencies) have implemented experimental sites.
These sites are located in various regions across the Amazon basin
including the Pantanal and Cerrado (savanna type vegetation) area
near Brasilia. Six of these sites have been chosen as CEOP reference sites, and they are operated by multinational group of scientists from institutions and universities located in Brazil, the USA andEurope.
At present, the LBA-CEOP reference sites are: (See Figure 1) (a)The Manaus site with two towers (K34 and C14) in primary forest;(b) The Santarém-Flona Tapajós site with three towers (K67 inprimary forest, K83 in selective logging and K77 in pasture); (c) The
Rondônia reference site, which has two towers on different surface
conditions namely the Reserva Biológica Jaru (forest site) towerthat stopped operating in November 2002, and the Fazenda Nossa
Senhora de Aparecida (pasture) tower; (d) The Caxiuana tower in

burn area) and Campo Sujo (a quadrennial burn area).
All the sites measure fluxes of carbon and surface energy, verticalprofiles of air temperature, CO2, and water vapour, as well as generalsurface meteorological variables, with time resolutions as high as 30
minutes so that they can be classified as CEOP 1-D sites. The
Manaus K34 and Rondônia sites also measure soil moisture andtemperature profiles, continuous soils respiration, and volatile organic carbon. The K34 site also features a tethered balloon and ahydrological catchment that is being discussed for use as a potential
LBA CEOP hydrologic reference site.
Figure 2 shows the diurnal variability of CO2 fluxes in four sites
during the dry season.
